You are in the 'know' Kassaundra. Many people consider these birds as merely ornamentals. I know there are plenty of other good breeds but these are what I was raised with and I am quite happy with them.
As mentioned, I intend to buy 25 Austra-Whites in Jan. but that will just be a 'project'. I love the Australorps equally and just want to 'play'...an old man's toy! lol
I am raising my chickens in a small town, chicken friendly, but still a town. Their space is about 1/3 acre and working on planting chicken friendly plants/shrubs/trees, so I don't have space for many diff breeds so for me the one chicken that does it all, and that I can still play w/ color/pattern for a diverse looking flock is the way to go. I came to them almost accidentally and am so glad I did.
